Deprecated. Please use oracle.xml.dbaccess.DBAccess

public class DBAccess

extends java.lang.Object

Maintains CLOB tables that can hold multiple XML and text documents. Each table is created using the statement: CREATE TABLE tablename FILENAME CHAR( 16) UNIQUE, FILEDATA CLOB) LOB(FILEDATA) STORE AS (DISABLE STORAGE IN ROW).
